4.1 Connection Diagram Overview
Figure 4: Typical connection diagram for the solar inverter system.
4.2 Installation Steps (General Guidelines):
- Mounting: Securely mount the inverter in a well-ventilated area, away from direct sunlight, moisture, and flammable materials. Ensure adequate clearance for cooling.
- Grounding: Connect the grounding screw (12) to a reliable earth ground.
- Battery Connection: Connect the 48V battery bank to the Battery positive (6) and negative (7) terminals. Ensure correct polarity.
- PV Input Connection: Connect your solar panels to the PV input (5) terminals. Observe maximum voltage and current ratings.
- AC Input Connection: Connect the AC input (14) from the grid or generator.
- AC Output Connection: Connect your household loads to the AC output (13) terminals.
- Communication Connections: For advanced monitoring and control, connect RS485/CAN (9), WiFi (10), or USB-B (11) as needed.
- Parallel Operation: If using multiple inverters in parallel (up to 6 units), connect them via the parallel communication port (16) as per the detailed parallel installation guide.
- Final Checks: Before powering on, double-check all connections for tightness and correct polarity. Ensure all circuit breakers are in the OFF position.
5. Operating Instructions
The Dawnice Solar Inverter offers flexible operating modes to optimize energy usage. The LCD screen (1) and physical buttons (3) allow for configuration and monitoring.
5.1 Powering On and Off
- To Power On: Ensure all connections are secure. Turn on the AC input circuit breaker (15), then the battery breaker, and finally the PV array breaker. Switch the ON/OFF rocker switch (4) to the ON position. The inverter will initiate its startup sequence.
- To Power Off: First, switch the ON/OFF rocker switch (4) to the OFF position. Then, turn off the AC input circuit breaker (15), followed by the PV array breaker, and finally the battery breaker.
5.2 Operating Modes
The inverter supports various charging and discharging modes, which can be configured via the LCD screen or connected communication interfaces:
- PV Only: Prioritizes solar power for charging and load supply.
- Mains First: Prioritizes grid power, using solar as a secondary source.
- PV First: Prioritizes solar power, using grid as a backup.
- Mains + PV: Combines grid and solar power.
The system intelligently manages power flow:
- During the day: Photovoltaic panels convert solar energy into direct current, which is fed into the inverter. The inverter supplies power to the load. Excess power charges the battery. Once the battery is fully charged, the inverter stops charging, and excess power can be transmitted to the grid.
- At night: The battery discharges to supply power to the load. If battery power drops to a protection level, the battery stops discharging, and the grid supplies power to the load.

6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Dawnice Solar Inverter.
- Regular Cleaning: Keep the inverter's exterior clean and free from dust and debris. Ensure ventilation openings are not blocked. Use a dry, soft cloth for cleaning.
- Connection Checks: Periodically inspect all electrical connections (PV, battery, AC input/output) for tightness and signs of corrosion or damage. Tighten any loose connections.
- Environmental Inspection: Ensure the installation environment remains within specified temperature and humidity ranges. Protect the inverter from direct exposure to harsh weather conditions.
- Firmware Updates: Check the manufacturer's website or contact support for any available firmware updates to ensure your inverter has the latest features and bug fixes.
- Battery Health: If using lead-acid batteries, regularly check electrolyte levels and terminal conditions. For lithium batteries, monitor their health via the inverter's display or communication interface.
